Application filed January 11, 1908. .Seria1'No.'410,'369.

T 0 all whom it may concern:

Be it known that I, FINLAY R. MoQUEnN, of Minneapolis, Hennepin county,Minnesota, have invented certain new and useful Improvementsin'Controlling Devices for Granariesand Bins, of which the following isa i specification.

The obfject of this invention is to providea means or controlling theoperating levers for grain bin slides, the apparatus shown hereln beingfor the same purpose as the device illustrated and described in mycompanion'application A herewith, filed Jan.

-11, 1908, Serial No. 410,368, and being of more simple construction andeasier of in stallation.

My invention consists generally in various constructions andcombinations, all as here- 'inafter described and particularly pointedout in the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a sectional view illustrating the application of my invention to abin. Fig. 2 1s a detail sec: tional view of the same. Fig. 3 is a planview illustrating the connection of the lovers with the bin slides. Fig.4 is a detail sectional view showing the device-for locking the leversagainst operation. Fig. 5 is a sec tional view on the line AA of Fig. 4.Fig. 6' is an edge view of the operating lever by means of which thelocking device is controlled.

In the drawing, 2 represents the bins having slides 3 connected at 4with. operating rods 5, 6, 7 and 8. Bars 9 are pivotally supported atpoints intermediate to their ends in a bracket 10 and pivotallyconnected at their lower ends to said rods respectively. The upper endsof the bars are connected by rods 11 with a series of levers 12, 13, 14and 15. These levers are pivotally mounted at 16 and extend up throughthe floor 17 in position to be grasped and operated by the attendant. Aplate 18 is slidable in guides 19 on said floor and has an opening 20through which the levers extend, said opening being of sufficient widthto receive the levers but too narrow to permit them to be oscillatedtherein except when opposite a slot 21 which connnunicatcs at one endwith the opening 20 and extends into the plate 18 to a point near oneedge. sufficient length to allow the plate 18 to be reciprocated andadjust the slot 21 opposite The opening is of 1 i any one of the leversbut only one of them at a time, and consequently one of said levers maybe operated to 0 en the bin slide while all of the others are ockedag'ainstoscillation. A lever 22 is pivoted at 23 andconnected by a link24 with the plate 18. oscillation of the lever 22 will reciprocate andpermit any one of them to be operated to open the slide.

I rave shown four levers, but a greater or less number may be employedaccording to the number of bin slides.

I claim as my invention:

.1. The combination, with two or more bins having discharge openings andslides therefor, of oscillating levers connected with slides andarranged in agroup side by side,

and movable means having an opening of suflicient length to receive theoscillating ends of all of said levers and said opening being ofinsufficient width to allow oscillation of said levers in said opening,and said open ing having an off-set adapted to receive the operatingends of said levers, one at a time when said offset is adjusted oppositea lever by the movement of said means, substantially as described.

2. The combination, with two or more bins having discharge openings andslides therefor, of operating levers connected with said slides, meansarranged in the path of said levers for preventing oscillation thereof,said means having an opening therein adapted to receive said levers oneat a time, and means for moving said oscillation preventmfi means pastsaid lovers to render their: operative or inoperative, substantially asdescribed. I

3. .The combination, with two or. more grain bins having dischargeopenings and 5 slides therefor, of oscillating ope-rating leversconnected with said slides, a sliding plate the plate 18,1'nove the slot21 past the levers.

havin an o )cnin to receive the ends of said i i 2-1 h levers saidopenings extending at right angles to the direction of movement of said10- vers, said plate having means whereby one of said levers may beoperated at a predetermined point in the movement of said plate leversto open its slide while 'all the other le vers are locked against suchmovement, and 1 means for operating said sliding plate Y 4. Thecombination, with two or more bins 5 having discharge openings andslides therei for, of operating levers connected with said cessivelypast several levers by the opera [5? tion of said plate.

In witness whereof, I have hereunto set .my hand this 4th day ofDecember, 1907.
